Purpose: The purpose of this study is to evaluate sexual maturation, attitudes toward sexual maturity, and body esteem in the sexual development of Korean elementary-school boys and girls. Methods: A descriptive cross-sectional study was conducted with 399 fifth and sixth graders (192 boys and 207 girls). The data were analysed with a $x^2$ test, t-test, and Pearson correlation coefficients. Results: Among the 207 girls, 70.5% had pubic hair growth, 68.1% had breast development, and 56.0% had a menstrual period. In boys, 59.4% of the 192 subjects experienced the development of external genitalia and 52.6% had pubic hair growth. Sexual maturation was related to grade (boys, t=7.07, p=.008; girls, t=12.76, p<.001), age (t=-2.20, p=.030; t=-4.11, p<.001), height (t=-5.16, p<.001; t=-7.52, p<.001), and weight (t=-2.89, p=.004; t=-5.19, p<.001) in both boys and girls. Girls were more likely to have sexual maturity than boys ($x^2=22.29$, p<.001). Boys showed more positive attitudes toward sexual maturity (t=2.10, p=.036) and higher body esteem (t=2.12, p=.035) than girls. Conclusion: This study shows that sexual maturation, attitude toward sexual maturity, and body esteem in sexual development differ between boys and girls. The findings indicate that it is necessary to develop a tailored sex-education program according to the sex of elementary-school children.

The Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome refers to a condition which presents as normal female secondary sex characteristics, normal external genitalia, congenital absence of the internal vagina, usually a rudimentary uterus in the form of bilateral noncanaliculated muscular buds, and normal tubes and ovaries with normal cytogenetic and endocrine evaluation, frequent association of renal, skeletal and other congenital anomalies. However, rarely, whole uterus or a segment of uterus may be present, but lacking a conduit to the introitus. If a partial endometial cavity is present in a segment of uterus, cyclic abdominal pain may be a complaint and furthermore endometiosis can be developed. Recently, we experienced a case of MRKH syndrome with the segments of uterus accompanying endometriosis in young woman. We present this case with a brief review of literatures.

A six-month-old Boston terrier presented with an extruded penis caudally, incompletely formed preputial sheath, bifid scrotum, retained testicle and deformity of the os penis. On physical examination, the urethral orifice was located on the surface of the perineum and a fibrous band was observed running from the grans to the urethral orifice on the perineum. The dog also had urethritis that was infected by ascending bacteria entering through the contaminated urethral orifice. Corrective surgery was undertaken to excise the external genitalia and retained testicle. The prepuce, penis and retained testicles were successfully excised. After the urethral orifice was cleaned periodically and antibiotics were administrated, recurrent urethritis disappeared. Using this therapeutic regime it is not necessary to reconstruct the anomaly located urethral orifice, if the location of urethral orifice is not the cause of recurrent urethritis and urinary incontinence.

Androgen insensitivity syndrome (AIS) is a rare genetic disease caused by various abnormalities in the androgen receptor (AR). The AR is an essential steroid hormone receptor that plays a critical role in male sexual differentiation and development and preservation of the male phenotype. Mutations in the AR gene on the X chromosome cause malfunction of the AR so that a 46,XY karyotype male has some physical characteristics of a woman or a full female phenotype. Depending on the phenotype, AIS can be classified as complete, partial or mild. Here, we report 2 cases of complete AIS in young children who showed complete sex reversal from male to female as a result of AR mutations. They had palpable inguinal masses and normal female external genitalia, a blind-end vagina and absent $M{\ddot{u}}llerian$ duct derivatives. They were both 46,XY karyotype and AR gene analysis demonstrated pathologic mutations in both. Because AIS is inherited in an X-linked recessive manner, we performed genetic analysis of the female family members of each patient and found the same mutation in the mothers of both patients and in the female sibling of case 2. Gonadectomy was performed in both patients to avoid the risk of malignancy in the undescended testicles, and estrogen replacement therapy is planned for their adolescence. Individuals with complete AIS are usually raised as females and need appropriate care.
Some species of true bugs have become serious problems in rice, upland crops, and tree fruits. It would be meaningful to understand research status by reviewing articles on those true bugs in Korea. Articles on those bugs published in several scientific Korean journals were reviewed, except articles on true bugs on rice plants; CD Part 1 included classification and morphological studies on eggs and larvae of Piesma spp., on external genitalia of Gonopsis affinis, and on spermathecae of some Podopinae and Asopinae species. $\circled2$ Development and growth analysis of Piesma sp., P. maculata, and 2 species of Coreidae were reviewed in part 2. $\circled3$ In part 3 we reviewed with major pest bug species on soybean, sweet persimmon, yuzu, citrus, chrysanthemum, and Cynanchum wilfordii, and insect fauna in mountain areas. $\circled4$ In part 4, damage levels in soybean, sweet persimmon, yuzu, grapes were reviewed. $\circled5$ ID In part 5 we reviewed seasonal occurrence patterns of Halyomorpha halys, Plautia stali, Riptortus clavatus in sweet persimmon orchards, of some species in soybean fields, of Nysius plebejus on chrysanthemum, and of Tropidothorax cruciger on Cynanchum wilfordii. $\circled6$ Chemical control methods in a sweet persimmon orchard, in grapevine yards, in a soybean field, and in a chrythansemum field were introduced in part 6. Some laboratory bioassay on insecticides against R. clavatus were mentioned, too. $\circled7$ Finally in part 7, researches on transmission by Halyomorpha halys and Cyrtopeltis tenuis of micoplasma-like organism which is a pathogen of paulownia withces' -broom to Catharanthus roseus were reviewed.

Purpose: Transgender is a disorder of gender identity, who have appropriate chromosomal, hormonal and anatomical characteristics corresponding to their sexual phenotype but feel strongly with respect to their sexual identity, that they belong to the opposite sex. There is a persistence discomfort and sense of inappropriateness about one's assigned sex in a person who has reached puberty. Transgender is a psychiatric problem, but surgical method provides more satisfactory adjustment for patients. In gender reassignment surgery for female to male transgender, mastectomy, nipple reduction, hysterectomy, oophorectomy and phalloplasty are included. And as the final operation, recommended for scrotoplasty and artificial testes insertion. So we investigated the necessity and method of scrotoplasty in the final operation of female to male transgender. Method: The authors have long term follow-up of 75 cases female to male transgender during January, 1991 to February, 2008. Among them, 13 cases were evaluated in this study. During phalloplasty, the labium major skin preserved. And this labium majoral skin flap was made for the neoscrotum. At least six months later, artificial testes were inserted in neoscrotum with local anesthesia. Middle sized (3 cm diameter) artificial testes(silicon gel or carving soft silicone implant) were used because of the limitation of the neoscrotum. We evaluated the questionnaire and interview about the postoperative satisfaction in configuration of reconstructed scrotum, and the necessity of operation, the postoperative psychosocioeconomic improvement and limitation of body exposure activities such as swimming, public bathing. Results: Based on this study, satisfaction of reconstructed scrotum after scrotoplasty was improved(92%). The necessity of scrotoplasty was in 92.3% and the postoperative psychosocioeconomic well - being improvement was 77% in answers. Less limitation of activities requiring body exposure was 54% in answers. Most of the patients were satisfied with the results of surgical operation inspite of the operative procedure had some postoperative complications. Conclusion: This study was reported that the scrotoplasty in female to male transgender is not only a conversion of external genitalia but also an improvement of psychosocial state. Most patients sincerely hope to this operation, so we improve our surgical method for more good results.

Purpose: Congenital absence of the vagina is a rare case. It occurs as a result of Mullerian duct aplasia or complete androgen insensitivity syndrome. The reconstructive modality includes skin graft, use of intestine and various methods of flap. We report a patient who underwent vulvoperineal fasciocutaneous flap to reconstruct congenital absence of the vagina, while the external genitalia and ovaries are normal. Methods: A 26-year-old woman presented with vaginal agenesis. Under general anesthesia, a U-shaped incision was made between the urethral meatus and the anus. The new vaginal pocket was created up to the level of the peritoneal reflection between the urinary structures and the rectum. Next, the vulvoperineal fasciocutaneous flaps were designed in a rectangular fashion. Flap elevation was begun at the lateral margin which the adductor longus fascia was incised and elevated, and the superficial perineal neurovascular pedicle was invested by the fascial layer. The medial border was then elevated. A subcutaneous tunnel was created beneath the inferior of the labia to rotate the flaps. The left vulvoperineal flap was rotated counterclockwise and the right was rotated clockwise. The neovaginal pouch was formed by approximating the medial and lateral borders. The tubed neovagina was then transposed into the cavity. Results: In 3 weeks, the vaginal canal remained supple After 6 weeks, the physical examination showed normalappearing labia majora and perineum with an adequate vaginal depth. A year after the operation, the patient had a 7 cm vagina of sufficient width with no evidence of contractures nor fibrous scar formation. The patient was sexually active without difficulty. Conclusion: Although many methods were described for reconstruction of vaginal absence, there is not a method yet to be approved as a perfect solution. We used the vulvoperineal fasciocutaneous flap to reconstruct a neovagina. This method had a following merits: a single-stage procedure, excellent flap reliability, the potential for normal function, minimal donor site morbidity and no need for subsequent dilatation, stents, or obturators. We thought that this operation has a good anatomic and functional results for reconstruction of the vagina.
Purpose: The purpose of this study was to explore the dosimetric difference between simultaneous integrated boost intensity-modulated radiotherapy (SIB-IMRT) and three-dimensional conformal radiotherapy (3DCRT), and the clinical outcomes of anal squamous cell carcinoma (ASCC) chemoradiotherapy featuring SIB-IMRT. Materials and Methods: This study included ten patients with ASCC who underwent chemoradiotherapy using SIB-IMRT with 5-fluorouracil and mitomycin C. SIB-IMRT delivered 54 Gy to each primary tumor plus metastatic lymph nodes and 45 Gy to regional lymph nodes, in 30 fractions. Four patients received additional boosts to the primary tumors and metastatic lymph nodes; the median total dose was 54 Gy (range, 54 to 60 Gy). We additionally created 3DCRT plans following the Radiation Therapy Oncology Group 9811 protocol to allow dosimetric comparisons with SIB-IMRT. Locoregional control, overall survival, and toxicity were calculated for the clinical outcome evaluation. Results: Compared to 3DCRT, SIB-IMRT significantly reduced doses to the external genitalia, bladder, and intestine, delivering the doses to target and elective nodal region. At a median follow-up time of 46 months, 3-year locoregional control and overall survival rates were 88.9% and 100%, respectively. Acute toxicities were treated conservatively. All patients completed radiotherapy with brief interruptions (range, 0 to 2 days). No patient experienced ${\geq}grade$ 3 late toxicity during the follow-up period. Conclusion: The dosimetric advantages of SIB-IMRT appeared to reduce the toxicity of chemoradiotherapy for ASCC achieving high locoregional control in the extended period.

Purpose : Child sexual abuse is a significant and serious problem that affects public health and society. Pediatricians are responsible for preventing and detecting sexual abuse of children. The aim of this study was to examine clinical findings of child sexual abuse. Methods : The authors retrospectively studied 292 patients between the ages of 0 and 18 who were referred for evaluation of sexual abuse to the Emergency Department of the National Police Hospital from Oct 1, 2001 to May 5, 2005. Results : Sixty three (21.6 percent) of sexual abuse victims were younger than 6 years of age; 89 (30.5 percent) were 6-12 years of age; and 104 (47.9 percent) were 12-18 years of age. Attack time was the most common between noon and 6 pm. Victims were attacked in their home or nearby (51.4 percent). One hundred fifty six (53.6 percent) offenders were accquaitances, thirty nine (13.4 percent) of whom were family members. The disclosure of attack by parents with abnormal physical symptoms was more common in younger children than in adolescence. Eighty nine (30.5 percent) victims had no specific physical findings, 51 percent had injury to the hymen, 37.3% had injury to external genitalia, and 4 percent had anal injury. One case of gonorrhea and thirteen cases of chlamydia were found. Sperm was found in 19 cases and acid phosphatase was positive in 28 cases. The absence of physical findings and laboratory findings was more common in younger children than in those in adolescence. The time interval from attacks to hospital visits had a significant negative correlation with age. Conclusion : For younger victims, the time interval from attack to hospital visitis was more prolonged. Victims may have no physical evidence of sexual abuse. Therefore, a careful history should be obtained and a through physical examination should be performed. Pediatricians must play a leading role in evaluation and treatment of sexually abused children, considering children,s growth and development. Coordination with other professionals is necessary to provide consultation, medical treatment, and legal assistance for the sexually abused children and families.
